SlPHON-REGULATOR FOR WATER-CLOSET TANKS.

SPECIFICATION formng part of Letters Patent No. 509,855, dated December 5, 1893.

Application filed July 14, 1893. Serial No. 480493. (No model.)

To al& whom it may cowcrn:

Be it known that I, ANDREW A. ALLAN, a citizen of the United States, residing at Boston, in the County of Sufifolk and State of Massachusetts, have invented a new and useful Improvement in Siphon-Regulators for Water- Closet Tan ks, of which the following is a specification.

This invention relates to si phon regulators for regulating the flow of waterin water closet tanks, and it consists in the novel construction hereinafter described, whereby the flow is regulated noiselessly and effectually, and the wash or flow made longer or shorter as desired.

In the accompanying drawings, in which similar letters of reference indicate corresponding parts,-Figure 1 is an elevation of my improved device, a small portion being represented as broken out, the apparatus being in position in a tank of which a small portion is shown in Vertical section. Fig. 2 is a vertical section of the device, taken on line x, Fig. 1. Fig. 3 is a plan View.

A represents an ordinary tank, and a is the normal water line. This tank may be pro- Vided with any suitable device, such as a float, for instance, for automatically replenishing it, such making no part of this invention.

B represents a siphon, the long branch B' of which extends through the bottom A' of the tank and connects With the water closet supply, and the short branch B" opens into the tank, preferably near the bottom.

C represents an air chamber, of which C' is the bottom or floor, said chamber extending from the part B' of the siphon by means of the walls D. An upright tube E extends centrally np from the floor of the chamber as shown, and its upper edge is equal in height to the wall of the chamber. A lid Fisadjustably Secured by means of a bolt b and suitable nuts d e to an arm H, which is hinged at H' to the branch B' of the siphon, so that when the lid is down, it rests on the upper edges of the wall of the air chamber C and the tube or well E. The under side of the lid is preferably provided with a non-metallic Washer F' to make the closing air tight. An

air tube I, open at both ends, extends from the air chanber C up to a point above the water line a, and supplies air to said chamber. It will be observed thatwhen the lid F is down, there is no connectionbetween the air chamber C and the siphon, the tubeE only connecting with the siphon by means of the passage D' formed bythe walls D. The chain J connects the lid with the pull or handle in the water closet.

When the apparatus isin the position shown in the drawings, that is, with the lid closed, the siphon is not working, as the passage D' thereto is closed by means of the lid F resting on the upper edge ot' the tube or well E, so that no Water can flow from the tank through said tube and passage into the longer branch of the siphon. The chamber C, which surrounds the tube E, is filled with air, the supply coming through the gipe I. If the lid be lifted by a pull on the chain J, water of course rushes from the tank through the well E and passage D' into the branch B' of the siphon, setting it in operation. A hollow adjustable plug or screw K turns in a correspondingly threaded hole in the bottom or floor of the chamber C, said screw having a passage K', one end of which opens into the chainber C and the other into a passage D' leading to the siphon. XVhen the lid is dropped into position after having been lifted by the user, the air passes through the tube I into the chamber C, taking the place 'of the water which is receding before it, and passing through the passage K' into the passage D' and thence into the siphon. The length of time taken to entirely replace the water which has filled the chamber C by the lifting of the lid and hence terminate the operation of the siphon, depends on the adjustment of the screw K, such adjustment of course rendering the mouth of the passage therein larger or smaller as the screw is sorewed up or down. Thus the length of the wash is regulated.

L is a tube connecting the air chamber C through its wall, at the point L', With the npper portion of the shorter branch B" of the siphon. The effect of this tube is to regnlate the wash and make itlong or short as desired, by breaking the column of water at the point at which the tube L enters the branch B" of the siphon. In other words, water siphons IOO through both the tubes L and B", comparetively slightly of course through the forner. When the water' from the chamber C, which has fiowed in from the tank by reason'of the lifting of the lid, has receded below the point at which the tube L enters the chamber C, air passes up through. said tube and breaks the column of water in the siphon as above nentioned. The flow of wa er from the chamber C into the tubeL is regulated by the adjusting screw N.

Having thus fully described my invention, whatlcleim, and desire to secure by Letters Patent, is-

l. The herein described improved, siphon regulator for Water closet tanks, comprising the siphon B B' B", the air chamber consisting of the wallsC and bottom Dand provided with the weil E connected With the siphon by the passage D', said chamber being provided with an adjustable connection with said passage, a lid or cover adapted to shut down upon the upper edges of said chamber and well,

and a tube, as I, connected with and edmitting air into seid chamber, substantially as set forth.

2. The herein described improved siphon regulato-.for Water closet tanks, comprising the siphon B B' B", the air chamber consisting of the walls C and bottom D and provided with the wellE connected with the siphon by the passage D', said chanber being provided with an adjustable connection with said passage, a lid or cover adapted to shut down upon the upper edges of said chamber and Well, a tube L extending from seid chamber to the siphon as shown and provided With an adjustable plug at the point of its conneci AN DREVV A. ALLAN.
